Ultimate Mono-Filament Structure

"UMISHIMA" ("UMI"=Sea, "SHIMA"= Island) is an original composite-structure technology developed by GOSEN, which combines different materials in monofilament.  UMISHIMA structure enables the creation of various string characteristics by changing the materials and number of the filament, that cannot be achieved by single-structure

A composite structure in which finer mono-cores (islands) are stacked with 1, 6, 12, and 18 in the base mono-core (sea)
